The only possible reason to use this module over JSON::XS is if you need to target a Perl older than 5.8.5 (which JSON::XS doesn't support). The documentation is largely a copy and paste job from the JSON::XS (an incomplete job, as there are MANY places where the POD still references JSON::XS instead of Cpanel::JSON::XS), and presumably so is the code. As for JSON::XS not having a public repo, please see http://software.schmorp.de/pkg/JSON-XS.htmlJames Wright
